A singlehollow die-casting forms the main n frame; part ofthemachinewhill includes the most of an expanded base 11,. the majonportionof a hollow substantially rectangular standard 2 which rises from thehollow base 1,and also comprises a top wall 3 for the upper end of thestandard 2, which forms the bottom of a container for the liquid. Thelower portion of the front of the standard 2 and the upper front portionof the base 1 are formed by a die-cast removable front door 4, which hasan interlocking engagement at its upper end as shown in Figs. 3, 8 and10, and which is secured place at its base end by means of an ordinarylock 5 which has looking detachable engage ment with the upper end of alock stud 6, se-

- cured to the bottom of a money pan 7 which telescopes into the bottomof the base 1 and is also removably held in place by means of the look5. Internal frame parts forcirrying various parts of the operatingmechanism comprise'a lower bracket member 8 Ywhich.

secured to the rear wall of the standard 2V by means of a pair of screws9, a mechanism frame 10 similarly secured to the rear wall of thestandard 2 by means of a pair of screws 11, and a dial-formingindicatorframe 12 in the upper and forward part of the standard 2 which issecured to the front and upper part of the mechanism frame 10 by meansof a pair of screws 13 which are screwed in from the back of themechanism frame 10, these frame parts 10 and 12 being pro-vided withabutting spacing bosses to receive these screws 13. These frame parts 8,10 and 12 may all conveniently be zinc die-castings.

An upright cylindrical glass container body 14 rests upon a shoulderformed within a peripheral upstanding flange 15 on the pro- ]ectingdish-shaped standard top 3 which thus forms the bottom ofthe container',this joint being provided with a gasket 16. The upper' end of the glasscontainer body 14 is provided with a die-cast cover cap 17 which isflanged downwardly around its periphery and is there provided with asealing gasket 18. VThe central portion of this cover cap 17 projectsupwardly in the form of a housing 19 for accommodating internalparts'which project upwardly above the top of the container body 14.rlhe front of this housing 19 is ofy circular shape and carries a nameplate 20 which indicates the use of the machine, that is, the nature ofthe liquid vended. The container body 14 and its cover cap 17 areVfirmly clamped and rigidly secured in place by means of three screwbolts or rods 21 which pass through the cover cap 17 and screw into lugs22 formed on the container bottom 3. Y

Near its rear edge the cover cap 17 is provided with'a screw plug 23 forfilling the container.

An upright pump cylinder 24 has its lower end securely sealed againstthe upper surface of the container bottom 3 by means of an interposedgasket 25 and is firmly secured to the container bottom by means of apair of screws 26 which pass through lugsas shown provided on the lowerend of the cylinder. The lower end of this pump'cylinder 24 is providedwith a sealed outlet or delivery passage 27 which entends laterally intoa lug 28 provided on the cylinder. A small delivery7 tube 29, which maysuitably be of copper, is sealed into the lug 28 in communication withthe cylinder passage 27 and together therewith forms a continuouslyfreely open outlet or discharge conduit from the bottom of the cylinder24. This outlet tube 29 extends upwardly above the liquid level andabove the top of the container body 14 into the housing portion 19 ofthe cover cap 17 and its upper end has a freely open outlet turneddownwardly. The down-turned upper end of the small outlet tube 29loosely enters and freely opens into the upper end of a considerablylarger vertical overflow pipe 30, which may be of brass, having itslower end screwed into he container bottom 3. A delivery spout 3lcommunicates with the lower end of the overflow pipe 30 and extends tothe outside of the Lmachine where it projects at the left side of theupper portion of the standard 2 below the container bottom 3. This spout31 may be a piece of bent copper tubing cast into the main frame part ofthe machine as an insert.

The pump cylinder 24 is provided with a pair of oppositely arrangedspaced upward extensions 32 which form a piston guide without addinganything to the effective length of the cylinder 24. Apiston 33 ofinverted cup shape is adapted to reciprocate into and out of the openupper end of the cylinder 24, being guided bythe guide extensions 32when it rises above the top edge of the cylinder 24 between these ratherwidely spaced piston guides. Since the piston 33 when it is reciprocatedrises at'its lower edge above the open top of the cylinder 24, it isobvious that this cylinder can then freely fill with the liquid withoutneed of providing any inlet valve for this purpose. However, in such aconstruction, when the piston rises in the cylinder, it would have atendency to draw air into the cylinder throughthe small outlet tube 29,after of course first drawing out the small quantity of the liquidcontained in this tube.

Therefore, the top web of the piston 33 is provided with a'suitablenumber of relief openings as shown in F ig. 5 which are controlled by aninwardly opening valve 34 of substantially a usual form. The cylinderpart may be a Zinc die-casting, while the piston and its valve maysuitably be of brass.

The piston 33 is further guided between the cylinder extensions 32 bymeans of a pair of' top extensions 35 on the piston which have innerplane opposed faces spaced apart to the same extent as the spacingbetween the piston guides 32 at their opposed edges so that thereby alarge slot is provided which comprises the space between the two pistonguides 32 and the space between the two piston extenrecesso4 sions 35. Apiston pin 33 extends between andi-shred at its ends in the respectivepiston extensions 35.

Anz operating link 37, which may be a brass stamping, is provided at itslower end with an eye by which it is pivoted on the piston piny 36.-This link extends upwardly at a slight outward: inclination and at itsupper end. is turned outward horizontally. This turned over upper end ofthe link 37 has rigid-ly connected thereto the u'pperend of a verticalslidable operating rod 38 which eX-k tendsdownward through and projectstor.k

some distance below' they container bottom 3. This connection betweenthe piston link o7 and the operating rod 38 is made by means of a ratherextended threaded portion on the upper end yof the rod which passesthrough-- the end of the link, which is {irmly held and clamped in placebetween a pair of nuts-319, thereby providing an adjustable connectionbetween the piston link 37 and its iperating rod 38 by reason oi which lpresently more cl-early appear, the piston 33 may be adjustably raisedor ylowered in 'the cylinder 34- for thereby varying the effectivelength of the stroke of the piston .vithout any change in the actuallength ot the path of( its reciprocating movement. ySuch adjustmentobviously will correspondingly vary the` measured quantity of the liquidlivered from the cylinder, by reason ot' tno' fact that the length ofthe path of travel et the pistonv within the cylinder below the up-yperend.v of the latter may thus be made longer or shorter.

The upper end of the operating)` rod 38 as well' as the piston link 37extends above the top of the container body 14C into the lowerl part ofthe housing 19. Theslidable openl ating. rod. 38 is provided with aguide tube lllforniing a liquid tight sleeve which at its upper end issomewhat above the upper end oli the container body 14 and which at itslower end screws with a sealing lit into the container bottom 3, whichit is shown nassing through and forming a rod guide therein (Fig. It maybe noted that the side of the hollow standard@ adjacent to its base land, in line below the spout 3l is provided with a drip trough 4l fromwhich any drinpings may drain into the casing andV be caught by themoney pan 7 trom which they will4 quickly and harmlessly evaporate.

In the embodiment of the invention shown thepiston 33 is normally at itslowermost position in' the cylinder d tion of the machineis lifted ou ofthe` inder and is again returned in its i stroke to its lowermost normalposition, thus performing a single complete recipi'ocaticn foreach timethe machine is operated. Thus the sliding operating rod-*38 ymay termeta lift rod since it iirst raises the piston 33 r before itimparts tothis piston its downward as will delivery stroke. The portion ofk thelift rod' 38 which. extendsbelow the container bottom 3 and. the lowerend of theguide sleeve 40 passes through and is slidably guided in abearing provided by they inner frame part or mechanism frameand this rodnormally projects freely downwardfbelow this bearing to an extentsubstantially equal to or a. little greater' than the extent of itssliding movement and terminates in a rounded lower end. T his litt rod38 is provided with a stop pin l2 which limits its downward movement byabutting againstA the top of the bearing 'formed by the frame part 10.Other stop means for this lift rod will hereinafter appear. Above thisstop pin there is a washer 3a-iid on the litt rod 38 interposed between;this washer and the lower end of the guidey sleeve 40 there is a ratherstrong coiled. thrustA spring Ll-t. lt will now be clear that iii theoperating rod 38 is lifted and then released the spring le will returnthis rod to its lowermost position and. thereby impart aA deliv-v erystroke toY the piston 33. Thelift rod 38 andL its guide sleeve l0maybeot brass.

A rockingoperatlng lever has a camy toe which enga-ges the rounded lowerend of the lift rod 3,8.k Forwa-rdly fromI the lower end' portion of thelift rod 38,*this operating lever 45 is pivoted on a pin 46 which iscarried by a pair of spaced forwardly'projecting ribs formed on theinner frame piece l0, the lever l5 being guided between these ribsas iscleari ly shown in the drawings. `Above and forwardly from its pivot pin46 theV operating lever ll'is provided with al relatively short tailarm'by which this lever is stopped against the lower side of theindicator trame 12, as shown in Figs. 3, 8 and 10, which thereby-alsoforms a further stop for the'lift rod 38 against the downward thrust ofits spring-44. The operating lever 45, hardened steel stamping, is ot'aflat substantially triangular shape so ythat virtually or in f inventionis concerned, any suitable manul ally operable device may be providedfor thus actuating or rocking the operating lever 45, such for exampleas a-usual simple form of plunger projecting from the front of themachine, or by means lor a simple rocking actuating lever provided witha suitable handle at the outside of the machine. However, in the moredesirable embodiment of which desirably is al the invention shown, themanually operable device for actuating the rocking operating lever iscoin controlled. These coin controlled parts of the operating mechanismwill bc described somewhat farther along, since at this point it isthought desirable to describe the mechanism of the hereinbefore notedindicating device which is employed in carrying out'the invention forgiving at any time a visual indication of the number of deliveryoperations to which the machine has been subjected. Such indicator maybe considerer, constituting a simplified form of cash register whichwill indicate thenumber of sales which have been made, andcorrespondingly of coursethe amount of cash which has been, oi' whichshould have been, tflren in, regardless of whether or not the deliveryoperations of thcinachine are controlled by the deposit or insertion ofa coin therein.

The indicator mechanism will now be described. A circular window openingis provided in the front and near the top of the hollow standard 2 andis closed by a glass plate 47, held in place by means of a bezel ring`48, which is flanged inwardly over the front of the glass and flangedoutwardly at the inner side of the wall of the standard. At its frontthe indicator frame 12 has a rather `deep flange which fits up againstthe edge of the glass 47 and its bezel ring` 48. rl`he eX- posed frontsurface of the front plate of thisl indicator frame 12 forms a dial,which in the particular construction shown in the drawings is graduatedor calibrated in units running from one to one hundred, every tenth unitbeing indicated by a longer calibration mark and by a single numeral,running from one t0 nine. excepting at the combined starting andVending` point at the top, which is left blank.

A large or long indicating hand 49 moves sten by step over the dial forgiving unit indications, thus moving` one step or unit indication ateach oneration of the machine, so that thereby obviously this long outeror forward hand 49 will directly indicate or count the operations of themachine unit by unit from one to one hundred. At the rear of the longhand 49 is a short or medium length intermediate hand 50. At eachactuation of the machine. this medium hand 50 moves angularly over onlyone-tenth of the dist-ance covered by the units hand 49. Thus when theunits hand 49 .has made one rotation. to give an indication of onehundred, then the medium hand 50 will have covered teu unit spaces andwill stand at the numeral 1 on the dial, thereby also indicating onehuncred. according to this hand 50. After this. for succeedingoperations of the machine, these two hands 49 and 50 are to be readtogether. For example, when the unit hand has moved again over the firstten units indication and reached the numeral `dium hand 50v reaches thenumeral 9, it will indicate 900. rl`h1s medium length hand 50 istherefore a hundreds hand. lnward from the intermediate medium lengthhundreds hand 50, there is small or short hand 5l, which is a thousandshand. by reason of the fact theJr in its movement it covers one-tenth'ular distance of the medium length or hundreds hand 50, correspondin lvcovers one one-thousandth of the angltance covered by the units hand 49.rllhus when this thousands hand 5,1 stands at the numeral 1 on the dial.it will. indicate one thousand. lt will thus be readily understood thatby reading the dial `.idi cations of the three hands together, unitindications up to 9.999 may be determined, which will then be 51 willnow be described. All of these hands are in axial alignment with theircommon aXis at the center of the dial. rlhe units hand 49 is carriedupon the forward end of a shaft 52 which extends to the rear through thedial plate of the indicator frame 12 and at its rear end is journaled ina bearing' provided on the mechanism fra-ine 10. rlhis shaft 52rotatably passes through and projects at both of its ends beyond anintermediate sleeve 53 which passes through the dial plate and at itsforward end carries themedium length intermediate hundreds hand 50.rlFhis intermediate sleeve 58 rotatablyv passes through and projects atboth of its ends beyond a shorter outer sleeve 54 which is joui'naleddirectly in the dial plate of the indicator frame 12 and at its forwardend carries the short or thousands hand 5l.

' A large spur gear 55 is fixed on the units hand shaft 59. adjacent tothe front side of its bearing in the mechanism frame This gear 55 formsa part of the operating mechanism for driving` the entire indicatormechanism, which will be presently descr-il od. lt may be noted,however, that this dri ing devicehfor Ythe indicator moves the gear 55for- Ward stepy by step to the extent of one units indication of theunits hand 49, each-timev that th-e hereinbefore described deliverymechanism is operated.

A Transfer vmechanism is provided between the units hand shaft 52 andthe hundreds 4This pinion 56 engages with a spur gearV which has.,formed 1n the same piece therewith as a hub on its forward side, a spurpinion I58 which engages with ak spur gear 59 fixed upon the rear end ofthe intermediate sleeve 53 which carries the hundreds indieating hand50. The pinion 56,y gear .57, pinion 58 and gear 59 constitutecontinuousv'ly engaged transfermeans from the units indicating 'shaft 52to the hundreds indicating 4sleeve 53, the ratio of which is as ten toone, that is to say, it will require ten rotationsof the shaft 52 inorder to impart one complete rotation to the sleeve 53.

Similar transfer means are provided from the hundreds indicating sleeve53 to the thousands sleeve 54, comprising a spur pinion 60 in the same.piece with and forming a hiubon the forward side of the gear 59,engagingvwith a spur gear 61 Acarrying on its forward side a spur.pinion 62 forming a hub thereon in the same piece therewith and whichis in engagement with a spur gear 63' which 'is fixed upon therear endof the short outer sleeve 54 which carries the thousands indicating handl. The ratio of this continuously engaged transfer gearing from theintermediate sleeve 53 to the louter sleeve 54 is also ten to one.

Thus it will be seen that the comparative extent of angular v'movementbetween the 4units*indicating hand 49 and the hundreds indicating hand50 is as ten to one, and simiV larly between the hundreds indicatinghand v and the thousands indicatingfhand'51 the comparative extentofangular movement is :also as ten to one, and that accordingly thecomparative extent ofthe angular movement between the units indicatinghand'49 and the thousandsindicating hand 51 is as one hundred to one.The two transfer gears 57 and 6l are independently loosely journaledupon a `stud shaft '64 which at kits forward' end is rigidly fixed .the`dial plate of the indi-` cator frame 12, the -rearmost transfer gear 57being positioned on the shaft -by the -f'ront face of 'th-e contiguousdrive gea-r 55.

The large drive gear `is continuouslyengaged with and is driven by apinion 65 which .formed in the saine piece and asa hub 'on' the forwardside of a ratchet vwheel 66. This ratchet vwheel 66 with its pinion 65..is journaled on the middle portionof a shaft 67, the rear end of whichenters themechanism frame l0 and `the forward end kof which enters therear end yof al boss 'formedonth'e indicator frame `12,*so that thisratchet wheel with its vpinion is .rotatively confined Ibetween thesetwo frames, with the upper portion fof the ratchet wheeljust at thereargof thelower portion the drive gear 55.

it will be noted that this ratchet wheelfshaft 6l" is located belowandconsiderablylto the left side of the gearshaftor units hand shaft 52 sothat the toothed periphery of 4the ratchet 66 is j ust at the left of avertical-,plane t passing throrwh the axis of the. shaft 52.

The ratio ofv drive foreach tooth, or from tooth to tooth, of theratchet wheel 66 vto the units indicating shaft 52 is as one hundred toone. rllhat is tofsay, each time the ratchet wheel 66 movesover ltheangular distance between two of its teeth, the units lindicating hand 49will move over a singleunits. indication on the dial. For example, theratchet wheel 66 mayV have twenty-five ratchetA teeth, itsl pinion 65may havev twelve teeth andthe drive gear 55 may have i fortyfei-ghtteeth. lt might be noted that this ratchet wheel together with all oflthe above described 4gear wheels in the indicator mechanism mayconveniently be Zinc `die-castings.

l The device by which the ratchet wheel 66 1s driven or actuatedstep bystep one tooth at a time vfor each operation of the above de scribeddelivery mechanism will now be described. 'Thisratchet wheel 66 isprovided with a holding pawl 68, shown as in the form of a bent leafspring the remote end ofl which is provided with an eye which 'fits overan anchor pin 69, which may be cast'upon the wall of the mechanism frame10 which extends just at the rear of the ratchet wheel `66. Thisspringholdingpawl 68 isprevented Vfrom rotating on its anchor pin 69 bymeans of a holding pin 70 which at its rear. end isy fixed in themechanism frame lO and thefforwa-rdly projecting yend portion of whichvis split to form a slot whichreceives the spring pawl 68 at anintermediate point thereonsuitably spaced from the anchor pin 69, as ismostlpclearly shown in Fig, 1l; The free end of this spring lpawl 68engages between two of the teetliof the ratchet wheel 66 for norinallyholding'V this wheel stationary while at j the same time providing forits rotative move-ment in one direction only when actuat ing'force isapplied thereto. VIn the construction shown,the direction of rotationofthis ratchet wheel '66 is counter-clockwise fas viewed from theAfront, vso that thereby its toothed periphery vat the right yside off lits shaft 67 will move upwardly.'

A spring-pressed pawl-'carryingoperating .lever 7l for the .ratchetwheel-'66 is pivoted 'iii on the front and near the lower right handcorner of the mechanism frame l0 on a pivot stud 72 which may becastupon this frame piece. This indicator operating lever 7l, which maybe a flat steel stamping, is straight along its lower edge and extendsto the left in the form of an arm, the free end portion of whichoverlies the slot formed between the guide ribs on the frame piece l0for the operating lever 45, which is a part of the ydelivery mechanismof the machine. It will be noted that flanges or webs are formed on theframe piece vl0 at opposite sides of the upper edges of the guide ribsand that the slot for accommodating the operating lever 45 extendsupwardly above these flanged ribs into the uprightvportion of the framepiece l0 at the back of the ratchet-operating lever 7l.

This ratchet lever 7l is in general of substantially triangular shape,thereby to providev thereon an upper arm which extends angularly inward.This ratchet lever 7l is vrovided with a fairly strong return spring 3,which is a coiled compression spring en Agaging over a small lug formedon the upper arm of this lever 7l and at its other end this spring 73 isseated in a socket-forming projection 7 4 on the front face of the framepiece 10. The ratchet-.operating lever 7l, which is a pawl lever,carries a spring driving pawl 75, the construction of which per se maybe the same as that of the holding pawl 68. The right or shank endportion of this sprin pawl, which carries an `eye at its end, is anciored in a slot cut into the pawl lever 71 from its left hand end, andfrom the point Where this flat spring pawl 7 5 emerges from this slotthe spring pawl, by reason of a bend therein, projects inwardly andupwardly with'its free end normally in engagement between two of theteeth of the ratchet wheel 66 at the right of the periphery of thelatter. n V Y When the pawl-carryin g lever 7l is rocked upwardly itsspring `pawl 75 will impart rotative movement to Vthe ratchet wheel 66and when this pawl-operating lever` 7l is released it will be returnedto its normal position `shown in the drawings by its spring 7 3, whichis stronger than thespring pawl 7 5, which accordingly will be movedover the teeth of the ratchet wheel v66, the latter being held againstreverse rotation by the holding pawl 68. In the operation of theindicator device, this operating lever 7l will thusl be lifted thecorrect distance for rotating the ratchet wheel to the extent of asingle tooth movement or step, the return spring 73 then acting t0 resetthe' indicator-operating lever 7l audits spring drive pawl 75 to normalposition, for a subsequent operation. In the embodiment of the inventionshown in the drawings, this indicator-operating lever 7l will be thuslifted by the upper edge portion of the underlying operating lever45-each time Lacasse this latter lever is operated for effecting'adelivery of a predetermined measured quantity of the liquid, ashereinbefore described.

The manually operable device for actuating the operating lever Li5remains to be described, and in the embodiment of the invention shown inthe drawings this i`s a coin controlled device, by reason of which thehereinbefore described delivery mechanism or dispensing mechanism isnormally inoperable, the manually operable operating device or drivingdevice being made effective for this purpose bythe insertion of aproper-coin. These `coin controlled parts of the complete operatingmechanism of the illustrated coin controlled vending machine will now bedescribed.

Near its upper end the front door'piece or plate 4L is provided with anouter recess 76 which forms the entrance way for a coin. This entraceway 76 is vertically of a flaring triangular shape, as shown in Figs. 3and 8, and has its upwardly and inwardly inclined bottom wall convexlycurved to fit the lower edge of a proper coin while it is open freelyoutwardly with a vilat downwardly and inwardly inclined upper wall forguiding the flat side of the coin. The coin is thence guided downwardlyat its edges in a coin slot 7 which at the front and in the lower partsthereof is in part formed by the inner inwardly and downwardly inclinedflat end surface of a lug 7 8 formed on the inner side of the door plate4 below the coin entrance 7 6. This colin slot 77 at its upper and innerpart is also in part formed by means of an inner coin guide 79 which isin the form of a short flat bar notched at the middle on its lower edgeand at its opposite ends rigidly secured in place on the inner side ofthe door plate l by means of a pair of screws 80, one of which ap earsin Fig. l0.

n operating handle 8l,which maybeazine die-casting, is shown at theright side of the Vmachine just above the base l as an upstanding leverarm to be pushed rearwardly and downwardly. This handle lever 8l has ahub portion 82 which is journaled in a bearing provided in the wall efthe standard 2. The notched and squared end portion of a handle shaft 83is cast as an insert into the hub 82 and adjacent end of the handlelever 81, whereby the handle 8l and its shaft 88, which may be of steel,are rigidly and firmly secured together. The other end of this handleshaft k83 is journaled in a bearing formed on the opposite wall of thestandard 2. llVithin the hollow standard 2 the handle shaft 88 carries acoin carrier 84 through the lower end of which it passes and in whichthis shaft is removably fixed. This coin carrier 84 is in general ofVsubstantially an inverted U shape as probably appears most clearly inFig. 7 with the handle shaft 83 passing through the lower ends of itsarms, so that this coin carrier 84 in general forms an upstanding leverwhich in its normal position projects upward ly at a forward inclinationas shown in Figs. 3 and 8.

rlhe coin carrier 84 at the lower ends of its spaced arms is shown asprovided with hub portions the ends of which fit up against the innersides of the opposite walls ofthe standvle ard 2 surrounding the handleshaft 83. vThe coin carrier 84 is firmly and rigidly secured to thishandle shaft 88 by reason of the squared end portion of the shaftadjacent to the handle hub 82 fitting snugly in a square hole throughthefadjacent coin carrier hub end, the handle shaft 83 being anchored tothis hub end of the coin carrier by means of-a screw 85 the inner end ofwhich engages in a recess 1n the squared portion of the handle shaft askshown in Figs. 2 and 7, Vso that thereby the coin carrier 84 and thehandle mal position the coin carrier 84 will be stopped by a pairof/rear oppositely opposed stop lugs 86 thereon abutting against thelowervsides of lateral forwardly projecting shoulders formed on thelower part of the bracket member 8, as shown. in Figs. 3, 8, 9 and 10.The coin carrier 84 at the left side thereof is provided with adownwardly projecting tail arm 87 t0 the e-nd of which there isconnected the forward end of a coiled retractile return spring 88 forthecoin carrier 84, the other end of this spring being an-v chored tothe adjacent wall of the standard 2 by means of a screw 89, as shownmore particularly in Figs. 3 and 8.

rlhe transverse bar of the coin carrier 84 at the top thereof isprovided 'on its rear side with a deep and wide transverse notch,forming opposed lateral shoulders, as shown in the drawings, moreclearly 1n Fig. 9. These shoulders, adjacent to rbut slightly spaced,rearwardly from the bottom of the large slot slots or grooves 90 arenormally 'in alignf ment with the coin slot 77, so as to receive thenserted coin 91 therefrom. j

The top bar of the coin carrier 84 has Va forwardly extending ledge 92which is arcuate on its upper surface and which along its upper sidemargins is provided with apair of arcuate ribs 93,- the Vrear ends ofwhich are in line vwiththe adjacent faces of the coin-receiving slots90, and the upper arcuate surfaces of which extend forwardly and'vdownwardly from the coin lslot77 along the lower correspondingly curvedsurface of the casinglug 7 8. The purpose of these ribs 93 is to providea rest for the Vlower edge of a coin should such coin be vinsertedthrough the coin slotl 77 while the coin 'carrier '84 is outof itsnormal position, that is, when the coin carrier has been rockedrearwardly. This prevents thelugs 86. The forward ends ofthese lug armsY 94 are connectedtogether by a 'cross piece or bar 95 the upper side of-*which is provided with a coin-guidingsurface 96, this surface fromfrontto rear forming an arcuate convex curve which is Ythe `same as thearcuate curve of the path oftravel of the coin carrier, this surface 96also being concavely curvedr from side to side or laterally to thearcuate' contour ofthe edge of the coin. This coin-guiding andsupporting surface 96 extends across from the front to the rear of thetop of the cross bar 95.

The rear side of this cross har 95 forms a substantially verticalsurface which is sul stantially in line with the aXis of the handleshaft or coin carrier'shaft 83, while the forward sideofthis cross vbartogether with` its coin-guiding surface 96 is somewhat forward of theradially aligned coin-insertion slot 77 and fthe coin-receiving slots 90in the coin carrier-84 when the latter yisin its normal position shownin the drawings.

hus an inaio serted coinsuch as the coin 91 in the coin carrv'rier slots90 will rest at its lower edgeV upon and be supported by the --curvedsurface 9G von the cross bar 95, which is cast in the same piece withthe bracket member 8. When the coin carrier 84 has been rocked toitsrearward position, the coin 91 will pass beyond the end of thecoin-supporting surface 96 and beyond the rear flat face of the bar 95,and' will accordingly be free to drop into the bottom of the casingwhere it will be received in the money pan 7 f f It will be noted fromthe drawings, lparticularly Figs. 8 and 10, that the hereinbef'o'redescribed operating leverl 45 has thereon a rounded downward projectionor lug 97 which is just at .the front of and in the path `of rearwardmovement ofthe upper edge por- V tion of the coin 91. Therefore, if thecoin carrier 84 is rocked while it carries a coin,

lthe exception that the pivot hole fo the coin carried thereby will rockthe operating lever 45 in the mann-er hereinbefore described, foredecting the delivery of a pre determined measured quantity of theliquid. When the coin carrier carries no coin, it is obvious that it mayrock freely back and forth without effecting any result. The coin 91merely forms a temporary extension of the length of the lever arm formedby the coinv carrier 84 and is then released from the coin carrier inthe manner above noted. When the operating lever 45 ias been thus rockedto its operated position, the resulting angularly inclined position ofits lug 97 together with the rounded contour of this lug will cause thislug to have a cam action upon the upper edge of the coin in the coincarrier by reason of which the coin is pushed downwardly, whichfacilitates the quiclr release and downwarddropping of the coin 91, aswill be readily understood.

It is important that the coin carrier 84 when itcarries a coin should.be compelled to move completely to its rearward position for dischargingthe coin without .permitting it to return from any intermediate positionto or towards its normal position in which it is shown in the drawings.Otherwise it is obvious that the coin carrier could be rocked back andforth to and from an intermediate position and unlimitedquantities ofthe liquid thereby obtained by the use of only a single coin.Accordingly, in order to prevent this, a pair of forwardly extendingcoin ratchetpawls 98 and 99 are located one at each side of the lowerportion of the operating lever 45,. and at the rear are pivoted on apin. 100 which extends between a pair of upstanding lugs 101 on the topof the bracket qmember 8, a spacing collar 102 (Fig. 9) beingl providedon the pivot pin 100 between these ratchet pawls. j

Each of these coin ratchet pawls 98 and. 99 is provided at its rear orpivoted end with a tail arm whi-ch projects downwardly Vbetweenthecasing wall of the standard 2 and the rear face of the forwardlyoffsetupper portion of the bracket member 8, each of these tail armsbeing urged rearwardly by a coiled'thrust spring` 103 which is seated ina socket provi ded in the back of the bracket 8. This bracket below andforwardly from the pawl pivot pin 100 forms a stop shoulder for both. ofthese coin ratchet pawls against which they are normally pressed bytheir springs 103, each of these pawls 98 and 99, however, actingindependently of the other.

These two ratchetpawls 98 and 99, wnich may be steel stamping-s, areboth ali' 1,.

tne pivot in 100 `in the left hand ratchet pawi locatedfarther forwardlyin the pawl arm than is the pivot hole in the right hand ratchet pawl 98(Figs-8, 9 and 10). YThe right handA ratchetpaw'l 98 projects wardly andterminates in a rounded end closely adjacent to the rear face of andnear the upper edge of the coin 91 in the coin carrier (Fig. 8), whilethe forward end of the similarly shaped. left hand ratchet pawl V99 is alittle farther to the rear (Fig. 10).

These pawls 98 and 99 each has a smooth shank portion adjacent to itspivot pin 100 after which for the rest of its length out to its forwardend it is provided on its lower edge with a series of ratchet teeth thefront faces of which incline rearwardly while the rear faces of theseteeth are abrupt, the notches provided between these teeth being adaptedto receive into them the upper edge of the coin 91 as it is movedforward by the coin carrier. lt is to be noted that the ratchet teeth ofthese respective pawlsalternate with each other, that is to say, thepawl teeth in one of the ratchet pawls come even with or opposite to thenotches between the pawl teeth in the other ratchet pawl. Thus when thecoin carrier 84 carrying a coin 91 is rocked rearwardly, the upper edgeof this coin will engage alternately with the teeth of the respectivecoin ratchet pawls 98 and 99, thereby cutting' in half the amount oflost motion in the return movement of the coin carrier with the coin,before such return movement is stopped by a tooth of one of the ratchetpawls. This arrangement renders it impossible to obtain more of theliquid than has been paid for. It also assures the delivery of a uniformmeasured quantity of the liquid at each successive operation of themachine. ln this connection, vit will be noted as obvious that thehomonologue of this feature could. also as well be embodied in asubstantially similar dispensing' device withoutcoin control, forsimilarly assuring successive uniform deliveries. y

The hereinbefore mentioned notch in the lower edge of the coin guide 79is to provide clearance for the lug end 97 of the operating lever V45and similarly for the forward ends los of the'coin ratchet pawls 98 and99, asbwill be. clear from Figs. 3, 8 and 10, so that these parts maycome close up to the coin 91. lt will be noted that the forward edge ofthe operating lever 45 near its lower end lug 97 is provided with arounded projection by which in its return movement this operating leverwill be stopped against the upper portion of the coin guide 7 9,additionally to the above notedstop provided by its top projec-V tionagainst the lower side of the indicator frame 12. Vf hen the coin dropsfrom. the coin carrier it will strike a. bell 104 for announcing to thecustomer that the machine has been fully operated.

lt isthought that the operation of all of theparts and features of thevending machine have been fully described in connection with thedescription of the construction and that therefore there is nothingwhich need be acne-din uns respect. c vending-machines constructed'substantially fas f shown 'in the drawings fand above 'describedhaveVbeen found Ito .operate'successfully,'substantially in the mannerhereinbefore described. 4
